Manganese

Test Kit for

Irrigation Water

ISTR38072 04/13

Manganese is not occurring in natural waters but it is

found in various salts and minerals, frequently associated

with iron compounds. Manganese salts are used as

fertilizer's additives, in ferroalloys (in the steel manufacture),

in non-ferrous alloys as it improves their corrosion resistance

and hardness.

Manganese is not considered to be toxic to man and

aquatic life and it is ingested as a trace nutrient, both in

food and water. Nonetheless manganese has been limited

in drinking water since it causes tenacious stains to laundry

and because it produces objectionable tastes in beverages.

Manganese is commonly found in domestic wastewater,

industrial effluents and receiving streams.

Note: mg/L is equivalent to ppm (parts per million).

SPECIFICATIONS

SIGNIFICANCE AND USE

CHEMICAL REACTION

INSTRUCTIONS

The reaction between manganese and reagents causes a

violet tint in the sample which is proportional to the

manganese concentration.

READ THE ENTIRE INSTRUCTIONS BEFORE USING THE KIT

• Using the plastic pipette, fill each

glass vial with 7.5 mL of sample (up

to the mark).

• Insert one of them into the left hand

opening of the checker disc. This is the

blank.

• Add to the other vial

Deionized Water up

to the 10 mL mark.

Replace the cap and

shake to mix.

• Remove the cap

and add 1 packet

of HI 93709A-0

reagent. Replace

the cap and swirl

to mix.

• Remove the cap

and add 1 packet

of HI 93709B-0

reagent. Replace

the cap and swirl

to mix.

• Wait for 1 minute

and 30 seconds to

allow reaction to

occur. This is the

reacted sample.

• Remove the cap and insert

the reacted sample into the

right hand opening of the

checker disc.

• Hold the checker disc so that

a light source illuminates

the samples from the top.

• Keep the checker disc at a distance of 30-40 cm (12-

16") from the eyes to match the color. Rotate the disc

while looking at the color test windows and stop when

you find the color match. Read the value in the result

window directly in mg/L (or ppm) of Manganese.

For best results: Perform the reading three times and

take the average value (divide by 3 the sum of the

three numbers). Intensely colored samples will make

the color matching difficult and they should be

adequately treated before performing the test.

Suspended matter in large amounts should be

removed by prior filtration.

Caution: Ultraviolet radiation may cause fading of colors.

When not in use, keep the disc protected from light,

in a cool and dry place.

Interferences: Calcium above 700 ppm, magnesium above

100000 ppm, chloride above 7000 ppm, iron above

5 ppm.
